On: Horrible edge cases to consider when dealing with ...

[dollardisco]

Ever since I started listening to emma essex's music I have found just how half-baked Unicode handling is, even in current year. Some of my favorite examples are:

    "⎆", by "HHSU 𓃚 𝕮𝖆𝖒𝖇𝖎𝖚𝖒, 𝕏𝕪𝕝𝕖𝕞,  𝓗𝓮𝓪𝓻𝓽𝔀𝓸𝓸𝓭", from the album "𝅙𝅙" (U+1D159);

    "♫♫♩♫‿♩ but it's 怒首領蜂 大往生";

    "ｒｔｒｃ{（''»''）²２}：≞（''»''０１）；";

[Cyykratahk → dollardisco]

Apple music dislikes the song "⎆" so much that it's entirely missing from the album in my account.

This got me to look up a UTF-8 to unicode code point command line tool, which it turns out is "uconv -x hex/unicode". The first one looks like mostly mathematical alphanumeric symbols:

I wonder if anyone has used characters in the unicode private use area. That could have interesting results.

I'm sure some of the characters got stripped out by hn.

I was surprised HN let 𓃚 through. Apparently not banning Egyptian hieroglyphs yet.
